What is Ethereum?
Ethereum is an open, decentralized blockchain network, as well as an infrastructure that supports developers in creating digital applications. Unlike blockchains primarily used for recording and transferring digital assets, Ethereum allows programs to be directly deployed on-chain and run automatically according to pre-defined rules.
These on-chain programs are usually referred to as "smart contracts." Developers can use smart contracts to build decentralized financial services, stablecoins, digital collectibles, blockchain games, identity systems, and other decentralized applications.
Who Created Ethereum?
The concept of Ethereum was proposed by Vitalik Buterin in 2013, followed by co-founders like Gavin Wood and Joseph Lubin participating in the project development. After development, testing, and early-stage financing, the Ethereum mainnet officially launched on July 30, 2015.
Ethereum does not have a CEO or a single controlling entity responsible for centralized management of the network. Protocol upgrades are usually progressed through public proposals, developer collaboration, and community discussions.
How Does Ethereum Work?
Ethereum is maintained jointly by nodes distributed across different regions. These nodes are responsible for storing blockchain data, propagating transaction information, and enforcing network rules. When a user transfers ETH, invokes a smart contract, or uses a decentralized application, the relevant operations are broadcast to the network, verified by validators, and subsequently written to the blockchain.
The Ethereum Virtual Machine (EVM) is responsible for reading and executing smart contracts, providing developers with a relatively standardized execution environment.
What is ETH?
ETH is the native crypto asset of the Ethereum network. Ethereum is the name of the entire blockchain network and application platform, while ETH is the digital asset used within this network.
When users send assets, deploy smart contracts, or interact with decentralized applications on Ethereum, they typically need to pay Gas fees in ETH. ETH can also be used to transfer value, participate in staking, and support various decentralized finance (DeFi) activities.
What is the Proof-of-Stake Mechanism?
Ethereum originally operated on a Proof-of-Work mechanism, relying on computing hardware to participate in block verification. In 2022, Ethereum transitioned to Proof of Stake through "The Merge" upgrade.
Under the proof-of-stake mechanism, validators participate in transaction confirmation and block generation by staking ETH, no longer relying on large-scale computational competition, significantly reducing the energy consumption required to run the network.
What Are the Uses of Ethereum?
- Decentralized Finance (DeFi) Conduct asset exchanges, lending, staking, and liquidity management through on-chain protocols.
- Stablecoins and Digital Payments Various stablecoins operate on Ethereum and its extended networks and can be used for transfers, settlements, and digital asset transactions.
- Digital Assets and NFTs Issue on-chain certificates representing artworks, game items, membership rights, or other digital content.
- Decentralized Applications (DApp) Create applications that do not fully rely on a single company's server, storing key rules, assets, and transaction records on the blockchain.
- Token Issuance and Community Governance Creating tokens through smart contracts for ecosystem incentives, service usage, or governance voting.
What Is the Difference Between Ethereum and Bitcoin?
Bitcoin focuses more on decentralized value storage and peer-to-peer asset transfer, while Ethereum is more concerned with programmable functionality. Developers can deploy smart contracts on Ethereum to build more complex digital services.
Both maintain blockchain data through distributed networks, but their design goals, operational mechanisms, and main applications are not exactly the same.
